Heat shock protein A2 (HSPA2), also known as HSP70.2, is a 70 kDa testis specific protein. HSPA2 is required for spermatogenesis and functions as a chaperone for the spermatid DNA packaging proteins TP1 and TP2. HSPA2 is also expressed in cancer cells where it is normally localized to the cytoplasm but migrates to the nucleus during heat shock. Within aa 529‑616, human HSP70A2 shares 99% aa sequence identity with mouse and rat HSPA2.

Detection of Human, Mouse, and Rat HSPA2 by Western Blot.
Western blot shows lysates of Jurkat human acute T cell leukemia cell line, NIH-3T3 mouse embryonic fibroblast cell line, and C6 rat glioma cell line. PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human/Mouse/Rat HSPA2 Monoclonal Antibody (Catalog # MAB6010) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for HSPA2 at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
Detection of HSPA2 by Western Blot
HSP70 regulated by spermine protected against testicular toxicity induced by TP in mice and TM4 cells. a mRNA levels of HSP70s after treatment with spermine or eflornithine, a polyamine pathway inhibitor. b The function of HSP70 was indicated by cell viability, MDA, and LDH levels after treated with a HSP70 inhibitor VER155008. The concentration of spermine was 6.25 μM. c Spermine increased protein levels of HSP70s and eflornithine decreased protein levels of HSP70s. d VER155008 reduced the protective effect of spermine in mice. EF: eflornithine. The concentration of TP used in this experiment was 80 nM in TM4 cell. *P < 0.05, **P < 0.01, and ***P < 0.001 (n = 6) Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/34758869), licensed under a CC-BY license.
